Hi;
I have built a DIY CNC plotter which I have been having problems with and started a thread here.
I have now managed to get both the X and Y axis working using a some stepper test code which just runs the motors clockwise and anti clockwise.
I am now working on the next step which is to send a Gcode image for printing and here in lies the next problem.
I am a little confused with how this is supposed to work. I understand that the Arduino needs to have code running on it to receive movement commands based on the image to be printed and I need software on my Mac to interpret and send the image data over the USB port to the Arduino.
Looking at various guides I think I need GBRL on the Arduino and Universal Gcode Sender on my Mac. After a lot of head scratching I have managed to get UGS working on my Mac but I now think my problems lay with the software on the Arduino.
I have followed several guides but none seem to be up to date with the latest Sketch (1.8.2) and I am not sure I have the Arduino software configured correctly. It seems that the code for GBRL is all embedded and not visible but how does it know what pins I am using??
Any help would be great
